Physical GeographyClass 12
Temperature, EMR, Insolation
Matter = “Stuff” All matter is made of atoms Atoms combine to form molecules
Energy acts upon, and changes matter
Matter and Energy
“Energy is neither created nor destroyed” It just changes form
Kinetic Energy is a form of energy. Kinetic Energy = movement energy =
temperature
Kinetic Energy
Temperature Scales
Electromagnetic Spectrum
Electromagnetic Spectrum
Longer -------------Shorter
Infrared Radiation
Ultraviolet
Incoming Solar Radiation Constant at top of atmosphere (when
averaged annually) ~1400 watts/m2
Insolation
Solar Constant
Fate of Insolation
Refraction
Do all wavelengths of light refract at the same angle?
What is causing the wavelengths to bend differently?
What’s happening here?
Albedo
What happens to absorbed
radiation?
Radiation
Heat Transfer
What methods of heat transfer are occurring here?
Greenhouse Effect
Greenhouse Effect
Latent Heat
Sensible Heat
Two Types of Heat
Phase Changes in Water
CONTROLS ON TEMPERATURE
Latitude
Mt. Kilimanjaro
Urbanization
Cloud Cover
Effect of Clouds on Temperature
Death Valley
Look at differences in temperature
Effects of Land vs. Water
On Temperature
Continentality vs. Marine Effect
Water has a moderating effect on temperature!
Inland vs. Coastal
Evaporation
Land heats quicker and cools quicker
than Water!!!!
Transparency
Specific Heat
Movement
and Mixing
Currents/ Sea Surface Temperatures
Warm Ocean Current
France vs. Newfoundland, Canada
Portland, Oregon
Leeward vs. Windwardside of continent
Landscapes
Glacier National ParkEast vs. West Side
USGS
Particulates and Gases
Particulates
Carbon Dioxide Methane Water Vapor
Greenhouse Gases
Phase Changes in Water
Layers of the Atmosphere
Normal Lapse Rate
Photosynthesis
Depends upon % of cloud cover Cloud type Cloud height Thickness (water content + density)
Impact of Clouds
Examine: Incoming shortwave radiation Vs. Outgoing longwave radiation
To understand actual effects:
Cloud Height
What about Jet Contrails?
